git clone https://github.com/hashneo/asp2dotnet.git

cd asp2dotnet

npm install

node app.js --base <root ASP directory> --page <start page> --project <project name> --out <target path> [--rabbit-hole] [--verbose] [--no-includes] [--overwrite]

--rabbit-hole = Follow linked ASP pages and try and process the whole site.
--verbose = Print more stuff to the screen
--project = Project which will be created.
--namespace = Namespace of the classes. If not specified, takes the project name.
--no-includes = Ignore processing include files
--overwrite = By default the program won't overwrite existing generated aspx and vb files, this ignores that.

And example would be:
node app.js --base c:\inetpub\wwwroot --page default.asp --namespace mynamespace --project myapp --out c:\inetpub\asp.net --rabbit-hole

var sourcePath = path.parse( searchString );
